Abstract We report a general chemical approach to synthesize strongly ferromagnetic rare‐earth metal (REM) based SmCo and SmFeN nanoparticles (NPs) with ultra‐large coercivity. The synthesis started with the preparation of hexagonal CoO+Sm ₂ O ₃ (denoted as SmCo‐O) multipods via decomposition of Sm(acac) ₃ and Co(acac) ₃ in oleylamine. These multipods were further reduced with Ca at 850 °C to form SmCo ₅ NPs with sizes tunable from 50 to 200 nm. The 200 nm SmCo ₅ NPs were dispersed in ethanol, and magnetically aligned in polyethylene glycol (PEG) matrix, yielding a PEG‐SmCo ₅ NP composite with the room temperature coercivity ( H _c ) of 49.2 kOe, the largest H _c among all ferromagnetic NPs ever reported, and saturated magnetic moment ( M _s ) of 88.7 emu g ⁻¹ , the highest value reported for SmCo ₅ NPs. The method was extended to synthesize other ferromagnetic NPs of Sm ₂ Co ₁₇ , and, for the first time, of Sm ₂ Fe ₁₇ N ₃ NPs with H _c over 15 kOe and M _s reaching 127.9 emu g ⁻¹ . These REM based NPs are important magnetic building blocks for fabrication of high‐performance permanent magnets, flexible magnets, and printable magnetic inks for energy and sensing applications.
